oo00oo that evic head is real interesting; still need to get the tubes to go with it though;
passthrough mode/onboard charging
unregulated mode
Neat.
I loved those things ever since they came out with the original version. The Easy head version is better - it's using the same higher frequency PWM that the eVic does. None of the added features on an eVic though - you could consider it "eVic lite." With the passthrough mode, for travel it's perfect. All you really need for bare bones traveling is the Easy head with tube, one battery in it, and a micro USB cable to charge it or use it. You can find a USB power source to plug it into just about any place.
Of course, it fits 18650 battery tubes as well. If the OP is looking for something really small in a PT diameter - and downright cute at that size - this does it nicely with the 18350 tube.
Pretty sure GoodProphets has an ECF coupon code. That, and they have put the Easy heads on sale before. (Ask me how I know... Bought two of them when they were $14.99)
Guys keep in mind that the OP said she has hand problems. Bottom firing mech switches don't work for everyone.
